This paper looks at how contemporary environmental (including climate) policy problems are phrased in terms of effectiveness, efficiency, and equity. The latter three concepts have served as foci of theoretical discussions among economists who analyse these issues and identify criteria that...

Determining the social cost of carbon emissions (SCC) is a crucial step in the economic analysis of climate change policy as the US government’s recent decision to use a range of estimates of the SCC centered at $77/tC (or, equivalently, $21/tCO2) in cost-benefit analyses of proposed...

This study analyses how linking emissions trading systems affects the economical aspects of climate policy at both national and international levels. The analysis focuses on cost-efficiency, distribution between participants, competitiveness and emissions targets. In addition we examine how...

Subglobal climate policies will be the norm for some years to come. However, several options exist for improving the efficiency of domestic emissions regulation. A prominent but contentious policy option for improving the external efficiency is the implementation of carbon tariffs on...

Climate physics predicts that the intensity of natural disasters will increase in the future due to climate change. One of the biggest challenges for economic modeling is the inherent uncertainty of climate events, which crucially affects consumption, investment, and abatement decisions. We...

We consider an empirical estimation of the Environmental Kuznets Curve (EKC) for carbon dioxide and sulphur, with a focus on confidence set estimation of the tipping point. Various econometric – parametric and nonparametric – methods are considered, reflecting the implications of...

The paper develops a two-region endogenous growth model with climate change affecting the countries' capital stocks negatively. We compare two different policies aimed at supporting less developed countries: climate mitigation by developed countries, which moderates the increase in stock...

This paper analyzes the potential welfare gains of introducing a technology transfer from Annex I to non-Annex I in order to mitigate greenhouse gas emissions. Our analysis is based on a numerical general equilibrium model for a world economy comprising two regions, North (Annex I) and South...

This thesis consists of four self-contained papers, which are all related to important environmental and natural resource issues from a developing country perspective. Paper [I] concerns climate policy and addresses the potential welfare gains of introducing a technology transfer from the North...

This paper evaluates the consequences of renewable energy policies on welfare and energy prices in a world where carbon pricing is imperfect and the regulator seeks to limit emissions to a (cumulative) target. The imperfectness of the carbon price is motivated by political concerns regarding...
